The present invention relates to new compositions of matter, more particularly it relates to wood oil lacquers.

e have found that very valuable non- 5 skinning lacquers, including varnishes, from wood oil or containing wood oil are prepared by adding thereto a small quantity of an aralkylated phenol, such as benzylnaphthol or benzyl henol. kylated p enol added may vary within the widest limits, generally our new compositions contain about 0.5 to 5% thereof, but it is of course understood that the invention is not restricted thereto and that one may depart from the limits stated without departing from the spirit of our invention. 7

ur new lacquers are not liable to skim ning. They yield a completely clear coat and dry with a high luster and hard elasticity. $0 The following exam les serve to illustrate our invention without imiting it thereto, the parts bein by weight:

Ezmmple z 1.4 parts of 1-benzyl-2-na hthol and 1 part of the cobalt salt of lino eic acid are dissolved in 100 parts of wood oil while heating; a non-skiimin varnish is thus obtained drying within a out 6 hours to form a clear lustrous hard elastic film without wrinkles.

80 Example 2.25 parts of calcium resinate are molten together with 50 parts of wood oil, the mass is diluted with arts of oil of turpentine and then 2 parts o a mixture of orthoand para-benz lphenol and 0.5 art of the cobalt salt of linoleic acid are disso ved in the mass while still warm. Thus a nonskinning lacquer is obtained drying within 5 hours when coated and yieldin a clear,

lustrous and extremely resistant fi In the annexed claims the term wood oil lacquer is intended to include also wood oil varnishes as well'as lacquers or varnishes oontamiug wood oil. We cla1m:-
